Electromagnetic heating is a process that uses electromagnetic waves, such as microwaves or radio waves, to generate heat in materials. This method is commonly used in cooking, where microwaves excite water molecules in food, causing them to heat up quickly. It is also utilized in industrial applications for processes like drying, curing, and welding. The technology works by converting electromagnetic energy into thermal energy, allowing for efficient and uniform heating. Unlike traditional heating methods, which rely on conduction or convection, electromagnetic heating can penetrate materials, making it suitable for various applications, including medical treatments and materials processing.
